High Concentration Ozone Monitor – BMT 965 Series

Manufacturer: BMT Messtechnik GmbH
The high concentration ozone monitor from the BMT 965 series is designed for continuous measurement of ozone in industrial gas streams using the ultraviolet absorption (UV photometric) method, a highly selective principle insensitive to other gases. These analyzers are suitable for high ozone concentration ranges up to 600 g O₃/Nm³ and can report results in multiple units, including g/m³, g/Nm³, mass %, and volumetric % as required for output monitoring and process control

The instrument provides fast, continuous measurement with high accuracy and linearity across its selected range and is equipped with a digital display for local readout plus standard 4–20 mA and 0–10 V analogue outputs for remote monitoring and integration with PLC/SCADA systems. UV photometers like the BMT 965 are commonly installed on the main line outlet of ozone generators to ensure accurate process control and safety compliance in industrial environments

Designed for robust industrial use, the analyzer typically features temperature and pressure compensation, sample gas filtering, and options for automatic zeroing to maintain measurement stability over long periods. Versions of the BMT 965 are available in panel‑mount, wall‑mount cabinet, and portable bench‑top configurations to suit different installation needs.
